Cook N Home 02497 8 Piece Nonstick Heavy Gauge Cookware Set, Black

Is this cookware set only for induction cooking or can I use it on a regular electric or gas stove?

Are they too too heavy???? I have seen some cookware being too heavy to a point its harder to wash by the sink. I am a college student!

Are the handles covered in plastic or rubber?

These say cadmium and lead free. are they also pfoa and ptfe free?
